To all whom it may concern:

Be it known that l, CARL @scan BERG, a citizen of the United States, anda resident of Everett,l in the county ot Middlesex and a State ofMassachusetts, have invented lmprovements in Machines for ProvidingClosures with Seals, of which the following is a specification,reference being had to the accompanying drawings, forming part thereof.

This invention relates to machines employed in the manufacture of bottlecaps and other articles.

A type of bottle cap that may be produced .15 by the present embodimentot the invention is made of sheet metal which is dished somewhat and isprovided with an annular tiaring fiance or skirt that is tiuted aboutits edge. The dished portion ot the cap vis furnished with a cushioningmember which usually comprises va disk of cork. In order to prevent thecontents of the bottle from coming into contact with the cushioningmember, it is customary to apply a circular seal or protecting memberthereto of substantially the diameter ot the end of the opening.,y inthe neck ot the bottle. This seal is usually secured to the cushioning`member by means ot' an annular 'flange formed "in thereon which isinserted into a circular cut or scoring made in the cushionino' memberand is held therein byA `trictional contact with the Walls ot saidscoring. `Usually the seal is made of thin ductile metal having: littlestability and hencethe flange thereof cannot be depended upon to resistdeflection if brou 'ht into contact with the surface of the cus ioningmember ot' Vthe bottle cap.` lt is therefore important that the 'Harigeof 40 the seal should be brought into accurate registry with the scoringin the cushioning' member before the seal and cushioning member arebrought toward each other to introduce? said tlangeinto the scoring.

One object ot' the invention is to construct a machine of the naturedescribed so that a seal or protecting;r member having allange or auextension may he accurately applied to a cushioning member et a bottlecap or` other closing'device used 'to close bottles, jars or othercontainers.

Another object of the invention is to construct a machine of this natureso that the seal or protecting member may be made from a strip ofsuitable material; that the cushioning member may be scored or vprovided with a receptacle for an extension ot said seal; and that such oerations may be so controlled that ultimate y -the said extension fromsaid seal may be brought into registrv With and be received by thescoring ot said cushioning member.

Further objects ot the invention will appeartrom the followingdescription.

The invention consists in the means Wherebythe progection of the Sealand the scoring` or depression ot the cushion member are brought intoregistry.

The invention also consists in the means for making the seal combinedwith the means for scoring the cushion member and the means wherebyaccurate registryot the elements may be eected.

The invention also consists in such other novel features of constructionand combination of parts as shall hereinatter he more fully describedand pointed out in the claims. F1gure l, represents a plan View of themachine.

Similar characters of reference designate corresponding partsthroughout.

Referring particularly to Figs. 1 and 3 of`the drawings.`the machine isprovided with a driving shaft 10 that is driveny from an suitable sourceof power by a driving Apu ley 124 mounted thereon, which pulley isadapted to be clutched -to the shaft by means of a common type ofclutching device 14. The drivin@ shaft carries a bevel gear 16 whichcontinuously drives a. bevel gear 18 that is journaled on a stud 20secured to the frame of the machine. The top side of the bevel gear 18carries a roll 22 which cooperates with. a radially slotted disk24 toimpart a uniform step by step movement to a shaft 26 to Whichthe disk 24is secured. u'.l`heupper end ot the shaft 26 carries a feed dial 28which is in sliding enga ment with a circular table 30 secured totherame of the machine. The intermittently rotating shaft 26 also carries agear 32, which, by operatively engaging gear teeth formed on theperiphery or a carrier or table 34, intermittentl rrotates the table intimed relation to the eed' dial 28. The table 34 in'turn imparts acorresponding intermitteru; movement to a disk carrier or table 36through the engagement of the gear teeth. on the periphery of said table34 with a gear 38 secured on the underside of the dislr carrier or table36. The table 36 is journaled on a stud 40 projecting from the Vframe ofthe machine and is held in place by a Washer 42 which is secured to thestud by a cap screw 44. y

The bottle caps which are indicated at a are presented to the machinefrom a suitable hopper through a chute 46, which is arranged toseverally deliver the caps to recesses 48, formed in the periphery ofthe feed dial 28, which recesses cooperate with the top side of thecircular table 30 and a peripheral dan e 49 on the table to form'pockets 50 for t e bottle caps. The relative timing ot the intermittentmovements of the feed dial 28 and the! rotating table 34 is suclrthatthe recesses 48 and` suitable spaced pockets 52 on the table 34 aresuccessively brought into registr after each movement of thejdial and tale and at a.

point beneath a plunger 54. (Fig. 2). When this occurs, the plunger 54is depressed to force the caps down through an opening 56 in thecircular table 30 and into oneof the pockets 52 in the table 34. As thebottle Levante caps are being carried intermittently by the table34,they are successively acted upon by a vscoring device 58 (Fig. 4)which forms an annular scoring or cut b in the 'cushioning member -o ofthe bottle caps. (Fig. 12). The caps are-then. successively transferredbeneath a diskor seal applying device 60 (Fig. 2) which attaches a sealto the cushioning member by forcing the flange upon the periphery oi'the seal down into the annu# larscorng in the cushioning member. Thecaps are then successively carried by the table 34 to a seal settingdevicel64. (Fig. 10)

which applies additional pressure toi the seals, and thereafter the capsare successively ejected from the pockets in the table 34 and dischargedfrom the machine through a chute 66 which is secured to the machineframe. The plunger 54, scoring device 58, seal applying device 66 anddisk setting device 64 reciprocate in unison and in timed relation tothe intermittent rotation of the table 34. To this end, .said devicesand plunger are-carried by a vertically reciprocating plunger 70 (Figs.il and 2) which is actuated by means of an eccentric 7 2 carried by thedriving shaft 10. The' plunger 70 is guided by a bearing 7l in the frameof the machine and by rodi-3,73, 7 3 securedto a cross bar 74 of theframe, which rods extend through apertures in lugs or brackets 7 5 76,Fig. 9, and its shank extends throughl and is guided in an aperture in abracket 78 secured by bolt 80 to the reciprocating plunger 70. Theplunger 54 is urged downwardly by a spring 84- coiled about a reducedportion of the shank ot the' plunger and interposed between a shoulder86 formed on the shank, and a sleeve 88 threaded into said aperture inthe 'bracket 78. The downward movement of the plunger 54 is limited bynuts 9U threaded on the upper end thereo The scoring device 58 (Figs. 1,4 and), comprises a scoring or cutting tool 92 secured. to the lower endof a spindle 94 which is mounted to rotate in a bracket 96 secured bybolts 98 to the reciprocating plunger Z6. rlhe pressure exerted Aby thecutting tool 92 is resisted by a thrust bearing 99 on the spindle 94,which bearing is interposed between a nut 100 threaded on the spindleand a horizontal armll which forms a part of the bracket 96. A slightclearance is provided between the upper surface of the part 100 and thelower stirfaee of the bracket 101.. rlhe spindle 94 is rotatedcontinuously during the operation of the machine by a gear 102secured'to the upper end thereof. which gear is operatively lverticalsha raffaele pins 108 by a block 110 secured to the lower end of a shaft112. The lshaft 112 is journaled in a bracket 114 that is secured to thecross bar 74 of the machine frame. A pinion 118 is secured to the upperend of the shalt 112 and is operatively engaged by a gear 120 that issecured to the underside of a 'sprocket Wheel 122,-j'ournaled lona stud124 which projects upwardly 4from the bracket 114. This sprocket wheel122 is driven by a sprocket chain 126 which connects the sprocket wheelwith av sprocket wheel 128 c rried by the upper end of a 130 that isjournaled in the frame of the machine. The shaft 130 is in turn drivenby a bevel pinion 132 secured to its lower end, which `meshes withiabevel gear 134 secured to the main shaft 10 of the machine. v

ln order to allow for the reciprocation of the scoring cutter 92, andstill el'ect conB tinuous rotation thereof, the pins 108 that connectthe gear 104 to the head 110 are secured at their lower ends to the gear104 and their upper ends are free to slide in apertures in said head.

When the scoring cutter 92 is broughtdown into 'engagement with thecushioning member of a bottle cap, as shown'in Fig. 4, it is necessaryto firmly hold the cap against rotation by the rotation of the cutter92,

otherwise the scoring-.would not be properly formed. Accordingly, theillustrated machine is provided with a presser `foot which firmly gripsa cap adjacent the periphery of the cutter when the scoring 'tool is'brought into engagement with the cap. This;

presser foot comprises a sleeve 136 that surrounds the cutter and itsupper end extends into and is guided by an annular recess 'in thebracket 96. I7lhe cylindrical sleeve 136 is also guided by pins 138 thatextend into apertures in the bracket 96. The sleeve 186 is v urgeddownwardly #by springs' 140 mounted in apertures in the bracket 96 andbearing on Ithe upper end of the sleeve, 4the downward movement of whichsleeve being limited bya shoulder 142 formed thereon engaging an-annularplate 144 secured to the bracket 96.

The seal receiving and applying devices which are equally spaced aboutthe peripheiy of thetable 36 also successively cooperafe with'avertically reciprocating cutting and stamping device 148. (Figs. 1, 2and 6.) located at the front of themachine. rlhis cutting and stampingdevice is'a'ctuated in timed relation to the table 36 sothat eachsuccessive movement of the table brings one of the applying devices 184into registry therewith. The seals are cut from a strip .sf of suitablematerial, which strip is fed in timed relation to the reciprocatingmovement of the cutting and stamping device 148 so that during a periodof retraction of such device, the forward end of the strip is ad--vanced into position to be acted upon by oft e -tormed in a collar 152,which is secured to the upper end Vof an elongated cylindrical bushing154, that in turn is'secured in an aperture in a bracket projectin fromthe tranne of the machine. lVhen t e seal applying device 184 is broughtinto registry with the cutting and stamping device 148, a sleeve 1.56thereof is depressed into contact with a cutting block 158 secured tothe collar 152. Such movement oi the sleeve also depresses an upwardlyspring pressed plunger 160 by the engagement ot a shoulder 162 formed onthe sleeve 156 with the head of the plunger 160.- 'The shoulder 162 andthe head4 et the plunger 160 are maintained in engagement by a spring164 coiled 4 about the shank of `the plunger and interpod between ashoulder 166 on'the sleeve 156 and a sleeve 168 secured to the shankofthe plunger. The sleeve 156 is normally maintained in retractedposition by a spring 170 .coiled about a reduced portion of the sleevereceive the upper end of the plunger 160,

so that the spring itself doeslnot act to depress the plunger. Upon 'theup stroke of the cutting and stamping device, a circular shearing edgeon the upper end of a sleeve 182 cooperates `With a correspondingshearing edge on the block 158; to cut aicir cularl blank fromthe stripa. immediately' thereafter a stamping member comprising a sleeve 186 isforced upwardly into the position shown in Fig. 6, which cooperateslwith the block 158 to form a )flange on the biank and thereby completethe 'formation of the" seal. The upturned llange on the seal usually isvery narrow, only approximately one-thirty second' of an inch, so thatthe in-l side diameter of the lower extension on the part 156 is madeabout onesixteenth ot' an inch smaller than the insidediameter of the Ypart 15.8.

-Upon the retraction of the seal-neceiving `[and applying device 184andthe stamping member 186, a plunger 188 that. is axially mounted inthe member 186' presses the seal against the. plunger 160 by the actionof its spring 190 until the member 186 has become disengaged from theseal. The seal is then held in the receiving and ap lyingvdevice:

a plunger rod 192 which is actuated by a.

cam lever 194 (Fig. 2) to which it is connected through a,\link 196. Thelever 194 is' pivoted at 198 on a bracket secured to the frame of themachine and its inner end is provided with a cam roll which engages agroove in a'cam 200. The retraction l of the plunger rod 192 acts nearthe limit of its down stroke tol retract the cutting member 182 byrtheengagement ofa collar 194 formed on the rod 4with an abutment 196 formedwithin a sleeve 198 to the upper end oit which sleeve the cutting member182 is secured. Upon the up stroke of th`e plunger rod 192 a spring 204which is coiled about the rod and. is interposed between a collar 205thereon andthe abutment 196 I of the cam lever.

on the sleeve 198 acts to bring the cutting edge of the member 182 intooperative engagement with the cutting edge of the cutting block'158, theupward movement of said cutting membery 182 beingl limited by the.engagement of a shoulder 206 thereon with the endl of the collar 152.

The strip s is fed to the cutting and stamping, devices by means of afeed roll 210 whichcooperates with .a table 212, over which table thestrip is fed from a roll R mounted between brackets 214 secured to theif'rame'ot the machine. The feed roll 210 is urgedl downwardly towardthe table by .being secured to an arbor 216, the ends of which extendthrough and are journaled in downwardly spring pressed 'blocks 218 thatare acted upon by. springs 220 coiled about screws 222 which extendthrough apertures in the blocks and are threaded into the brackets 214.The intermittent movement is imparted to the feed roll 210 by a gear 224secured to one end of the arbor 216 which, through gears 226and 228 isdriven byl a gear 230. rlhe gear 230 is loosely mounted on a stud 232secured to one' by a cam lever 240 pivoted at 242 on the frame of themachine, the lever 238 being provided with a slot at its lower end whichis engaged by a lpin 244 on the upper end rIhe cam roll 246 on the camlever engages the groove of a cylindrical cam 248 that is' carried b I acontin,

uously rotating shaft 250 Ajourna ed in bear ings in lthe'frame of themachine and driven byfa sprocket wheel 252 thereon, which is connectedby a. sprocket chain 254 to asprocket wheel 256 on the main shaft 10. I.It will be understood, that as the seal receiving and applying devicesare brought into registry with the cutting and stamping device 148-that-the will `successively receiveV completed sea s` and thereaftersuccessivelybring them into position so that their flanges accuratelyregister` with the engage and depress the plunger v160 of the sealreceiving and applying device against the action of 'the spring 1 64, sothat the fiange of the seal is accurately and firmly pressed into thecushioning member. The

'fact that the plunger 258 is spring pressed downwardly ensures a dwellin the application of pressure to the seals and thus permits the escape`of air pocketed under the seal and which otherwise `might unseat theseal. In order to insure that' the seals will be firmly applied to thecushioning members of the caps after being acted upon by the plunger258, they are successively advanced to register with the seal settingdevice 64. rlliis device comprises a block 260 (Fig. 10) mounted toslide upon a bolt 262 threaded into an aperture in a bracket 264 securedto the plunger '70. This block is arranged to adjust itself to the topsurface of the seal and apply a decided pressure thereto during the downstroke of the plunger' 70 by means of a spring266 coiled about the bolt262 and interposed between the bracket 264 and the block 260. Thedownward movement- .of the block 260 on the bolt 262, during the upstroke of the plunger 70, is

limited by thehead 268 at the lower end of said bolt.

After the seals have been acted upon by the setting device 64, thebottle caps are successively advanced into alinement with the chute 66at which time the are elevated above the pockets in the table 34,preparatory to their being discharged into the chute 66. To this end,the bottom of each pocket in the table 34 consists of the top surface ofa vertically sliding block 270 (Fig. 8), the lower end of which block isprovided with a cam surface 272 that engages a stud 2774 projectingAupwardlyfrom the table 34 at a point in alinement with the chute 66,so

that as the pockets approach this point, the

blocks 272 ride up on the stud 274 to ele-A vatethe caps. The caps arethen discharged into the chute by means ofa fingerv 27 6 that is securedto a rod 278 pivotally mounted in y invasie brackets on the frame of themachine- This linger is normally held against a stop 280 on the frame ofthe machine by a spring 282 coiled about the'rod 278c The nger 276 isactuated to discharge the caps into the clinte 66 by means of a stud 282secureci to the plunger 70, which, upon the down stroke ofsaid plunger,engages a pin 281i projecting from the rod 278,V thereby actuating thefinger to discharge the caps. After a pocket passes by the stud 27a itsblock 272 is permitted to drop by gravity to its normal position. Toassist in securing accurate registration between the pockets in thecarriers or turrets 36 and 34:, the carrier 36 is providezl with aseries of holes 289 which are bashed to receive a pin 291 projecting(lovvnvvarflly from a short lateral extension ofthe arin 176. This pinenters one of the holes 289 at each downward stroke of the plunger and.corrects any' inaccuracy in the registration of the pockets in the tvvocarmers.

After. the caps have been discharged by the ejector 276 the plugs 2170in the pockets 52 in the carrier 34C may remain in their raised;positions, ancl in order to ensure their return Vto the properpositions, a pin 293 is secnreol in a bracket 295 carried by the pliunfger or head; 70 in the proper position to strike eacli plug 270 andforce it clownwarolly before it arrives in position to receive anotherbottle cap.
